I did it!

Many months ago Aiden started showing some interest in using the potty. We bought him a "Cars" potty and he used it a couple of times and then lost interest. About a month ago he started showing interest again, but we weren't very good at being consistent about it. In the last week or so he has gone and sat on the potty on his own numerous times. He always has his clothes on though.
This weekend I started putting him on the potty just before bedtime and nap time, and just after waking up from nap time. This evening, before bed, I put him on the potty and gave him a book to look at so that he would stay sitting long enough to possibly do something. Next thing I know he hops up and he had gone pee in the potty! I cheered for him and told him he did a great job. He instantly ran out to the bedroom, where Jay was sitting, and told Jay, "I did it!" He was so excited and proud of himself. I gave him two mini m&ms and we told the pee goodbye as it flushed down the toilet.
I know that this is just the beginning of potty training, but he was so proud of himself, and at under 20 months, I'll take it!
